one of together wit the maradapted for the reception. of the block 10 gins of these members will touch each other as illustrated in Fig. 2 so as bothto increase the strength of the construction and to prevent the formation of a slot or groove which,

uniform thickness and made by cold rolling ordinary flat sheet steel. The portions of this ring within and adjacent to the flanges 66 are illustrated as swelled outwardly as at 9 to form a substantially cylindrical shelf for the reception of the side rings. These shelves are not essential to the performance of my invention but are of practical importance in the provision of a rim in which the side flanges can be reversed since if the side rings are forced to seat upon the cylindrical surface of the middle or base rings, they will necessarily be of too great height and-too great curvature topermit of their being reversed so as to receive tires of standard shape and sizes.

One end of the base ring 5 is preferably made square as shown at 7} in Fig.4 and the opposite end is preferably beveled outwardly as illustrated at 7*. Also for the purpose of sustaining the outward thrust of the wedges or wedge rings when the rim is in position upon the wheel and for the pyrpose of safeguarding the middle ring against accidental collapse prior to being mounted upon the rim some securing device is preferably employed for securing together the ends of this base ring. Many devices could be employed to this end and the particular type of device is entirely independent of the construction and mode of operation of the base ring and side rings.

The device illustrated in Fig. 4, which constitutes one device I may thus employ, forms the subject-matter of a separate aplication, filed September 2, 1913, Serial No. $87,784, out of which the present application has been divided. This illustrative device comprises a block 10 rigidly secured to the inner face of the base ring-adjacent to the squared end 7 and having an abrupt engaging shoulder 11 at the side opposite the end of the ring. Secured to the opposite end 7 of the base ring and projecting be yond such end is a rigid metallic tongue 12 firmly secured thereto as by riveting or welding and having a notch or recess 13 one end of the notch or recess being formed with an abutment shoulder 14 adapted to engage snugly the shoulder 11 of that block.

The parts are so fashioned that when this engagement takes place only sufiicient clearance is leftbetween the ends 7 and 7 for cured to the inner face of the base ring 5; The distance between the block 19 and the 1 end of the tongue is such as to permit the insertion of a suitable prying tool therebetween and the end of the tongue. is here shown as formed with a tool receiving recess 20 adapted for the reception of a screw driver blade or the like. The thickness of the tongue 12 at the point opposite the recess 13 is preferably such as substantially to engage the outer face of the circular memher when the rlm 1s posltioned thereon thus absolutely preventing the possibility of accidental displacement. Any suitable interfit ting means may be employed for preventing slipping or creeping between the rim and the felly band. In the present embodiment the block 19 is illustrated as formed with-a thickened portion 24 forming a driving block and adapted to fit between fixed lugs 2525 carried by the felly band.v Also any suitable or convenient part of the rim may be formed for the reception of the, valve stem; in the present embodiment the drivw ing block 24 is apertured forthe valve stem as illustrated at 26.

It will be seen that this construction secures the middle or base ring rigidly against expansion so that the proper setting up of nearly or quite impossible to pry one of these ends over the other even in the absence of any securing means. desired to make the device absolutely fool proof it is merely necessary to undercut the end of the block 10 as shown at 37 and similarly undercut the end of the recess 13 as shown at 38. The smallest length of the recess is greater than the eatest length of the block so that these un ercut portions are normally spaced apart as shown in Fig. '4 and have no effect upon the normal operation of the device. the gap between the ends 7--7 these shoul- 4 the wedge rings will insure rigid securing of the tire or any However, if it be Upon the-closing of ders will be forced tightly together and the middle ring locked against col apse until the deflation of the tire.
